Duel calculator for the Yu-Gi-Oh!

Auto-completion of digits enables input with minimum tap operation.
It also has a log function. Life point changes are automatically noted.
In addition, you can use undo/redo function with the arrow buttons on the bottom of log screen. No more careless miscalculations.

After entering and calculating numbers with the calculator, you can manipulate values by pressing the "Damage", "Recovery", and "Set" buttons on the player's side to control life point.

You can even set your favorite wallpaper from the menu tab!

------------------

There was a major renewal in version 4.0.0.
The entire app has been redesigned to support a variety of device sizes.
- Dark mode is now supported.
- Add undo/redo functions at the log screen.
- Add support for setting UI transparency. You can combine it with the wallpaper.
- Add a preview of the digit to be entered on next tap. It is now easier to understand the next digit to be entered.
- It is also compatible with iPad SplitView.
- The in-app browser is no longer needed because devices can switch between applications at high speed these days, so it was discontinued.
